' will have the marginal edge thereof so disposed that the air will pass across the opening, drawing air outwardly from within said body. To produce such an outward flow of air, at the present time small windows are employed which are pivoted near their forward end to be swun outwardly into the air stream. Sliding windows are also employed forming a narrow opening near the front pillar to have the air flowing around the pillar pass over the opening and cause an outward flow of air from the body.

The present invention utilizes the same principle of projecting the air stream along the body over an opening formed by the sliding movement of a window. This is efiected by a frame at the trailing edge of the window which forms a seal with the edge of the body defining the openingv In a windshield construction, the windshield may slide in the plane in which it is disposed, to have an opening appear adjacent to the header or front terminal end of the roof. The windshield is provided with a frame which forms a seal with the marginal'front edge of the roof and when separated therefrom forms a deflector for the air. The deflector directs the air stream over the opening and the front terminal edge of the roof to cause an outward flow of air from the body through the opening. A similar deflector may be provided on the rear edge of a side window which forms a seal with the door pillar or body. and provides a deflector when the window is open for directing air across the opening.

Accordin ly, the main objects of my invention are to provide a window glass with a frame which forms a seal with the marginal edge of the body defining the window opening and which. when forming an opening with such edge. directs the air from the glass when the body is moving; to slide an angularly disposed windshield in its plane to form an opening with the marginal front edge of the roof and to direct air from the windshield over the opening when the body is moving; to provide a windshield with a frame which forms aseal with the top marginal edge' of the roof and a deflector for the air imping- 5 ing on said windshield to provide a more effective seal when closed and to produce an outward flow of air from the body when open; to provide a sliding window in a vehicle body having an element near the trailing edge for directing air from said window to cause an outward flow of air from within the body, and, in general, to provide ven-' tilating means for a vehicle body which is simple in construction, positive in operation and economical of manufacture.

Other objects and features of novelty of my invention will be either specifically pointed out or will become apparent when referring, for a better understanding of my invention, to the following description, taken in conjunction with the accompanying drawing, wherein Figure 1 is a sectional view of a front end of a vehicle body, embodying features of my invention;

Referring to Fig. 1, I have illustrated a vehicle body, having a cowl l0, windshield pillars II, and a header l2, joined to form a windshield opening l3. A slidable windshield I4 is employed to close the opening, being disposed in guide channels located in the pillars II. V A receptacle I5 is disposed below the cowl [0, in rear of a dash panel it, for receiving the windshield l4 and for collecting any water which may flow downwardly from the windshield l4. Suitable mechanism H is carried on the receptacle 15 for raising and lowering the windshield l4 oper ated by a crank handle I 3 which is disposed in a recess I9 provided in the dash panel l6.

Fig. 2 is an enlarged view illustrating the upper end of the windshield l4, and the lower portion of the header panel l2. The header panel I2 is provided with a recess 2! which receives a portion of a rubber sealing element 22 provided on the upper edge of the windshield l4. The rubber sealing element 22 is provided with a. sloping lip 23 on its outer portion, the upper edge of which is substantially flush with the header panel l2. The lip 23 forms a deflector for directing the flow of air over the windshield l4 outwardly over an opening 24 and the header l2. The flow of air in this manner, when the opening 24 is of small dimension, causes an outflow of the air from the inside of the vehicle body to thereby provide no-draft ventilation thereto. When the windshield I4 is raised the rubber sealing element 22 engages the recess 2| on the header to effectively seal the top edge of the windshield l4 therewith. This seal is aided by the deflection of the air over the joint formed between the element 22 and the header panel [2 which provides an area of reduced pressure at the joint and thereby assists in the sealing of the windshield with the header panel.

In Fig. 3, I have shown a modified form of deflecting structure wherein a metal frame 26 is provided about the edge of the windshield M, the top edge of which has a deflector portion 21 which joins with the panel l2 and which when slightly spaced therefrom produces an outflow of air from within the body. The header panel I2 is recessed at 28 and is provided with a projecting portion 29, which mate, respectively, with the edge 3| of the frame 25 and with a recess 32, provided frontwardly thereof. A rubber sealing element 33 is secured to the projection 29 and recess 28 to aid in sealing the joint between the frame 26 and the header panel l2. The function of the deflector 2? is the same as that of the lip portion 23 of the element 22 illustrated in Figs. 1 and 2 as described above. The deflector is available to produce an outflow of air, and for aiding in sealing the joint, between the windshield and the header when providing a low pressure area thereat. It is to be understood that when the windshield is lowered a sufficient amount the deflector will no longer be effective for producing an outflow of air and that air will blow directly through the vehicle body over the heads of the omupants, which in some instances is desirable.

In Fig. 4, I have illustrated a further form of my invention, wherein the windshield M has a frame 35 thereabout, the outer top edge being provided with a deflector portion 36 which mates with the header panel l2. A rubber sealing element 3? is secured to the edge of the panel i2 and employed for sealing the frame portion 35 therewith and for also sealing the deflector ele ment 36 through the projection of an extending portion 2-38 on the sealing element between the frame portion 35 and the deflector element 36. ihe function of the deflector element 36 is the same as that herein described relative to the structure shown in Figs. 2 and 3.

Fig. 5 illustrates a further form which my invention may assume, that of having a deflector portion 3-5 adhesively secured to the upper edge of the windshield hi. The element 4! may be of glass or other transparent substance such as a cellulose compound or it may be constructed from any translucent or opaque material. The header panel i2 is provided with a channel 42 having a rubber sealing element 43 which receives the upper edge of the windshield I4 in the conventional manner.

In Figs. 6, '7, 8 and 9 I have illustrated a form which my invention assumes when applied to a side window in a vehicle, which may be in the door, a side panel or elsewhere in a vehicle body.

In Fig. 6, I have illustrated a vehicle body having a front door M, in which a window 45 is disposed, for horizontal and vertical movement. The rear edge of the window 45 is provided with an element 45 having a deflector portion 41 adjacent to the reveal portion of the door panel 48. Suitable mechanism is provided for raising and lowering the window 45 and for advancing it frontwardly after it is raised for producing an opening between deflector 47 and the door panel portion ii Such an opening provides an outflow of air from the vehicle body due to a flow of air over the windshield 45 deflected by the element 47 over the opening. Suitable operating mechanism known in the art may be employed for producing the compound movement of the window 65 from a single operating element.

In Fig. 8, I have shown a modified form of structure for deflecting air from an opening at the side of the vehicle. Window 45 is provided with a rubber sealing element 49 which is similar to element 22 described in relation to Figs. 1 and 2. When the window is moved horizontally forward of the body, an opening is provided at the rear edge of the window 45 over which air will be deflected by the outer sloping surface of the element 49 as it passes along the window to cause an outflow of air therethrough. A suitable element 5| is provided in the frame of the door for abutting the rear edge of the element 49 to form a seal therewith. The sealing of the joint between the rear edge of the window 45 and the door is assisted by the flow of air over the joint which provides a reduced presslu'e area therewith.

While I have described and illustrated several embodiments of my invention, it will be apparent to those skilled in the art that various changes, omissions. additions and substitutions may be made therein without departing from the spirit and scope of my invention as set forth in the ac companying claims.
